What steps will reproduce the problem?
Honestly, I'm not sure.  I just logged in one day and it wouldn't work on my warlock until I cleared the SavedVariables.  Works fine now but it was kind of an odd glitch so I thought I'd bring it up.

What is the expected output? What do you see instead?
The expected output is for the addon to buff when I click the button.  Instead, it spits out an error log when I login.

What version of the product are you using?
3.2b

Do you have an error log of what happened?
This is the isolated error log - the glitch persists when only Smartbuff is active so I'm sure it's not an addon conflict.

Please provide any additional information below.
Just spat out this error one day.  I'm kind of bummed, I tend to forget to buff myself when I'm not grouped, so Smartbuff was a huge help.  I prefer it over the other buffing addons so I wish it worked properly  :(
